摘要：
A new method of electrode impedance measurement has been presented. A non-stationary voltage signal has been used as a perturbation, the frequency of which is an exponential function of time. The application of a modified short time Fourier transformation (STFT) to analysis of the voltage perturbation signal and the current response allows the determination of impedance spectrum.
